CEDAR researchers develop blood test that identifies pancreatic cancer with 85% accuracy

CEDAR researchers have developed a new blood test that could help detect pancreatic cancer earlier. The test, “protease activity-based assay using a magnetic nanosensor” (or PAC-MANN) uses a small blood sample to detect changes in protease activity — a key indicator of pancreatic ductal adenocarcinoma (PDAC), the most common and deadly form of pancreatic cancer.
The study detailing the new test was published in the journal Science Translational Medicine. CEDAR assistant professor Jared Fischer and research engineer Jose Luis Montoya Mira are the corresponding author and lead author, respectively.
“The problem with pancreatic cancer is that we often catch it too late,” Fischer said. “Our goal with PAC-MANN is to give clinicians a tool that can detect the disease much earlier, when more treatment options are available and there is a better chance of survival.”

Josh Moreau lab explores the role of B cells in non-lymphoid tissues.

Scientists are uncovering new insights into B cells, which are immune cells long recognized for their role in producing antibodies. A review by OHSU researchers published in Nature Reviews Immunology, reveals that B cells do much more. They work directly at areas of inflammation, where they become long-lasting cells that stay in the body. These cells can affect how diseases progress and how the body responds to treatments.
Joshua Moreau, assistant professor in the Division of Oncological Sciences and a member of CEDAR, is corresponding author on the review along with Lauren Rodda, assistant professor of molecular microbiology and immunology in the OHSU School of Medicine. Researchers are working to identify definitive markers for tissue-resident memory B cells and to map the molecular pathways that govern their activity. Gaining a deeper understanding of tertiary lymphoid structures formation and function could lead to new treatments that harness B cells to fight infections and cancers more effectively. OHSU News has more information on the report.
CEDAR researchers profile protease activity in PDAC cancer
Pancreatic cancer is challenging to detect early, and biopsy is higher risk than for other cancers. Using a low-cost, high-throughput assay, a new study from CEDAR researchers demonstrates there is a unique protease activity "signature" made up of specific substrates for pancreatic ductal adenocarcinoma (PDAC) that differs from benign pancreatic disease.
Once research establishes what specific substrates are present, a simple and inexpensive assay can be developed, potentially providing primary care physicians a tool to expedite diagnosis for patients. This could have a particular impact on growing cancer disparities in Black communities, where rates of pancreatic cancer are highest.
The paper, by first author and CEDAR senior research assistant Morgan Stewart, senior author and CEDAR Assistant Professor Adem Yildirim, and a team of CEDAR researchers, is available in Scientific Reports.

CEDAR interns represent in international science competition

Five CEDAR interns from OHSU's Summer Equity Research Program (Shawn Ichikawa, Chivon Ou, Shelby Sawyer, Matthew Tokuda and Gavin Magill) competed in the International Genetically Engineered Machines (iGem) Competition in Paris from Oct. 26 to Oct. 28, 2022. The team developed its cancer early detection project with CEDAR mentors Michael Brasino, Joshua Saldivar and Carlos Origel Alberto Marmolejo.
The project seeks to create a more accessible, cost-effective alternative to the present models of detecting the overexpression of c-Myc mRNA. Their aim was to create a cancer early-detection diagnostic tool that most clinicians can acquire to determine if their patients may have cancer by taking their patient’s blood sample and inputting that sample onto an agar plate with bioengineered E. coli bacteria, which is designed to proliferate only in the presence of cancerous c-Myc mRNA. You can read more about their project at iGem's Wiki.
Blood test developed by CEDAR researchers holds promise for early treatment

CEDAR researchers have devised an accurate and novel way to test blood to see if a pre-cancerous condition is escalating to outright cancer—potentially enabling treatment early in tumor development when cancer is more likely to be curable. The team, led by Thuy Ngo, a member of CEDAR and associate professor of molecular and medical genetics in the OHSU School of Medicine, developed a test that looks for cell-free messenger RNA biomarkers to distinguish multiple myeloma blood samples from non-cancer samples with 90% accuracy, and multiple myeloma from its pre-malignant condition with 100% accuracy.
They were able to distinguish liver cancer samples from noncancer with 93% to 100% accuracy, and liver cancer from cirrhosis with 100% accuracy. The research, published in NPJ Precision Oncology, lays the foundation for developing inexpensive assays that measure levels of cell-free RNA in blood for a small panel of genes that can differentiate cancer from pre-malignant conditions. Ngo and OHSU have filed a patent on their findings. More information on this research is available from OHSU News.
The importance of accelerating early-detection research

Cancer early-detection research can transform patient survival, but there are still significant obstacles preventing the translation of new research findings into the clinical setting, assert leaders of the field, including CEDAR's Sadik Esener and the Knight Cancer Institute's Lisa Coussens, in a new publication in the journal Science. Around half of all cancers are diagnosed at an advanced stage, despite the fact that treatments stand the best chance at improving survival when implemented early.
“Late-stage detection of cancer is a global problem that is exacerbated in resource poor settings, demonstrating that equity is a considerable challenge,” the authors observe. “Patients diagnosed with later-stage cancer can miss the window for curative intervention, and expensive later-stage systemic treatments are often associated with severe side effects and worse outcomes.”
At CEDAR, researchers are investigating cancer's early changes, and applying this knowledge to work on new, inexpensive screening tests, determining which cancers need vigorous early intervention, and directing precision therapies to reduce drug toxicity. You can read more about the article's findings on the Knight Cancer Institute's Cancer Translated blog.
Ece Eksi discusses new clues to prostate cancer

CEDAR postdoctoral scholar Sebnem (Ece) Eksi spoke with the Knight Cancer Institute's Cancer Translated blog about findings that could help identify more dangerous prostate cancers earlier, giving researchers new tools to stop them. Only a fraction of prostate cancers become life-threatening, but predicting which ones is challenging.
Eksi and her team found that two signaling proteins used by nerve cells can become active in and around prostate tumors, and may play a role in driving the cancers to be deadly. She discussed the discovery, published in Nature Communications, with Cancer Translated, including how the findings could help molecular biologists working on other cancer types.

Defense Department Idea Award for CEDAR's Thuy Ngo

Thuy Ngo, Ph.D., received a Peer Reviewed Cancer Research Program Idea Award from the Defense Department for a project to identify blood biomarkers for early diagnosis and treatment monitoring of liver cirrhosis and cancer. Ngo is an assistant professor of molecular and medical genetics in the OHSU School of Medicine and a member of CEDAR, the Knight Cancer Institute's Cancer Early Detection Advanced Research Center.
Liver cancer, or hepatocellular carcinoma, is the fourth leading cause of cancer-related deaths worldwide. Clinical blood tests have low sensitivity to detect liver cancer at early stages and are not effective for the reliable diagnosis of cirrhosis, which puts people at high risk of liver cancer. Patients with liver cancer are often diagnosed with inoperable disease. The Defense Department's $769,996 award supports Ngo's proposal to identify cell-free RNA biomarkers (including messenger RNA, circular RNA, transposable elements and microbial transcripts) that can detect cirrhosis and monitor its progression to liver cancer.
Thuy Ngo awarded Komen grant
The Susan G. Komen Breast Cancer Foundation announced 30 new grants to leading researchers across the U.S. and Canada — including CEDAR member and assistant professor of molecular and medical genetics Thuy Ngo, Ph.D. Ngo was awarded a Career Catalyst Research Grant to study the use of cell-free RNA found in blood as a way to monitor if a treatment is successful for patients with metastatic breast cancer. This method provides the opportunity to gain a deeper understanding of the behavior and characteristics of the metastatic tumor, and to monitor changes in metastatic lesions and responses to treatment. A full list of 2021 research grants can be found at Komen.org.
CEDAR/SMMART collaboration receives funding from the Kuni Foundation
The Kuni Foundation awarded almost $1.5 million to a collaborative project between CEDAR and SMMART, a first-of-its-kind platform designed to rapidly identify combinations of drugs that can stop tumors before they adapt and become drug-resistant. Currently, patients must have two biopsies at a major cancer center to enroll in the program. This is a barrier for people who lack the means to access a major cancer center, including rural, BIPOC and underserved communities.
The project, "Blood Biopsies as a Cost-Effective Approach to Democratize Personalized Therapy for OA & WA Patients," is developing approaches that will decrease the need for surgical biopsies by analyzing blood samples for material that escapes from tumors and goes into the bloodstream. This blood can be drawn at any clinic and shipped to OHSU. The award features CEDAR's Thuy Ngo as a co-investigator. Gordon Mills, director of precision oncology at the OHSU Knight Cancer Institute, is the principal investigator.

Using radiation to boost circulating DNA for ‘liquid biopsies’ of cancer

Testing for tumor DNA in blood is easier and safer than taking a biopsy of tumor tissue. The problem is, early-stage tumors may not shed enough DNA to find in a blood draw. Researchers at OHSU are working on a way to use radiation to increase the amount of tumor DNA in blood. They’ve shown that patients with suspected lung tumors show a sharp increase in circulating tumor DNA after treatment with stereotactic body radiation therapy, or SBRT.
